Electrical Steel Guide: Grain-Oriented and Non-Oriented Silicon Steel

Electrical Steel Guide: Grain-Oriented and Non-Oriented Silicon Steel

Short answer: Electrical steel is a low-carbon silicon alloy engineered for low core loss in magnetic circuits; grain-oriented grades serve transformers and non-oriented grades serve motors and generators, supplied from the alloy basis in our Alloy Steel Supplier page and the procurement route in our Import Steel from China Guide.

What Electrical Steel Is

Electrical steel (silicon steel) is a low-carbon alloy with 0.5 to 3.0 percent silicon that lowers core loss and increases electrical resistivity in transformers and rotating machines. The alloy basis is in our Alloy Steel Supplier page.

Grain-Oriented vs Non-Oriented

Grain-oriented electrical steel (GOES) has magnetic properties aligned to one direction for efficient transformer cores. Non-oriented electrical steel (NOES) has uniform properties in the plane for motors and generators.

Tip Silikon Use
GOES about 3.0 percent Transformers
NOES 0.5 to 3.0 percent Motorlar
Non-oriented low under 0.5 percent Jeneratörler

Key Properties to Specify

Buyers focus on core loss (W/kg at a given frequency and flux density), permeability and lamination thickness. Verification is in our Quality Inspection Guide and the document detail in our Mill Test Certificate Guide.

Forms and Supply

Electrical steel is supplied as thin laminations or coils; compare stock forms in our Steel Coil Buyers Guide and the energy context in our Metal for EV Guide.

Specifying and Sourcing

State grade (for example M19, M36), thickness and loss target; plan quantity with our MOQ and Lead Time Guide and price with our Price Quotation Guide.

Sıkça Sorulan Sorular

What is the difference between GOES and NOES?

GOES is directional for transformers, NOES is uniform for motors and generators.

Why add silicon?

It lowers core loss and resistivity for efficient magnetic cores.

What is core loss?

The power lost as heat in the steel during magnetization, in W/kg.

How is it supplied?

As thin laminations or coils to control eddy currents.

How do I specify it?

Give grade, thickness and target core loss.
